Abstract
The invention provides a terahertz frequency band local oscillation source based on a frequency multiplication link circuit integrated structure. The terahertz frequency band local oscillation source comprises an upper cavity body (1) and a lower cavity body (2); after the surface of the upper cavity body (1) is closely attached to the surface of the lower cavity body (2), an input port (22), a Y-shaped power divider (17), a first preceding-stage frequency doubler (19), a second preceding-stage frequency doubler (20), a Y-shaped combiner (18), a back-stage frequency doubler (21) and an output port (23) are formed. According to the local oscillation source, on the basis of a balanced type frequency doubler circuit, two stages of frequency doubling circuits are integrated into the same cavity body module, the structure is made to be compact, the defect of reflection caused by connection of port surfaces of different modules is overcome, frequency doubling performance is improved, thereby a W-waveband source is converted to the terahertz frequency band through frequency doubling, and larger output power is obtained.
